9
Width 2 to 9 Width of input port B0; if shorter than 9 bits it is sign-extended. For
example, if the width is 8, a value of 0x7F means +127 and a value of
0xFF means -1.
Register Port Registers input port B0
Input Port B1
Width 2 to 9 Width of input port B1; if shorter than 9 bits it is sign-extended. For
example, if the width is 8, a value of 0x7F means +127 and a value of
0xFF means -1.
Register Port Registers input port B1
Input Port C
Use Constant Sets input port C to constant
Constant Value (Hex) -2
35
to (2
35
- 1) Two's complement value of C, if C is constant. Values shorter than 35
bits are padded with zeros. Negative values must be a full 35 bits wide.
Width 2 to 35 Width of input port C; if shorter than 35 bits it is sign-extended. For
example, if the width is 8, a value of 0x7F means +127 and a value of
0xFF means -1.
Carry In Carry in for C (if C is not set to constant)
Register Port Registers input port C and Carry In (if C is not set to constant)
Output Port P
Register Port Always selected Registers output port P, CDOUT, and Overflow/CarryOut
Overflow/CarryOut None, Overflow,
